EXPLOSIVE FUEL MIXTURE AND METHOD OF MAKING THE SAME.-

No Drawin 3'.

To all whom it may concern: Be it known that I, JOSEPH E. BABB, a c1t1- i zen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and, useful Improvement in Explosive Fuel Mixtures and Methods of Making the Same; and I do hereby declare the following'to be a full, clear, and exact description thereof.

My invention relates to a fuel mixture for use. ininternal combustion engines, forthe purpose of permitting increase of compres sion and effecting more uniform compression in the engine cylinders.

One object of my invention is to provide a lead compound that is soluble in gasolene, kerosene and other motor fuels, to increase the effectiveness thereof, but which is nevertheless not dangerous to the life and health of those enga. ed in its manufacture.

Another ob ect of my invention'is to provide a mixture containing lea'd soap that issoluble in gasolene and benzol, which does not belong to the alkyl and phenyl compounds, nor to the ethyl or methyl groups of hydrocarbons, (of the type formulas CnH 2n+2 and CnI-I 2n, for example.

Another object of my invention is to provide an improved .mixture andjmethod of making the same that is of simple composition, effective in use, and which is not dangerous to the operator either during the stages of manufacture thereof, or when ready for use. I

I have found that by mixing distilled rosin or distillation products of rosin with.

an oxide'of lead, in the manner hereinafter described, a lead soap is formed that is solublein. asolene, to the extent of 10%, and is solub e inbenzol to the extent of by Weight. When this solution is mixed with gasolene in such quantity that the lead con tent thereof is one-thousandth part of the Whole,a very satisfactory motor fuel is secured, which will permit of materially in creased compression without producing knocks.

In practicing my invention, I first subject the rosin todistillation, preferably'in a fire still. The resultant distillate is popularly known as rosin oil. Rosin oil is a commercial commodity and I.may prefer to purchase it in-the'open market.

In the manufacture of my lead compound,

saturation.

Application filed. December 15, 1924. Serial N 0. 756,071.

the distilled rosin is heated in an open fire kettle to a ten'lperature of perhaps 140 C...- v

The foregoing form's What I term a lead I soap and is soluble in gasolene and benzol, to the extent of 10% and 50%, respectively,

or the solution may be of any strength below The soap is also soluble in acetone which may be employed instead of gasolene, or benzol. This concentrated solution may then be added to the main body of the motor fuel, preferably in such amount that the portion of lead in the fuel is 1 to 1000.

Lead soap may be manufactured also b first neutralizing the rosin acids with an kali such as caustic soda or otash, to form a soluble soap and then adding a soluble lead salt, such as lead chloride or lead acetate, to change soluble soap toinsoluble lead soap. The lead soap is subsequently washed to free it from the soluble alkali salts and then dried. Thereafter it may be mixed with gasolene or benzol, as in. the case of thelead soap made after the method above described.

Furthermore, in place of the distilled rosin above described I may employ products obtainable by distillation of crude gums such as'fossil gums similar to kauri m,

"manila copal, or varnish gums, from w ich rosin and turpentine are obtained, or from those gums of the conifer species which may be employed in forming soluble lead soa s .either through direct combination with t e lead or by the distillation process.

, I may also employ the resinous element to increase the solubility of metallic soaps other than lead, to thereby render them soluble in benzol, gasolene, acetone, and liquid fuels.

It will be apparent that I do not limit. .myself to the precise steps and proportions set forth in the foregoing specification, but my invention is limited in scope only to the extent definedin the accompanying claims.

I claim as my invention: 1. Afuel composition comprising an explosion motor fuel and'a gum of resinous character that is soluble in gasoline, comdistillation product of rosin, adding thereto a lead oxide in sufiicient quantity to substantially neutralize the acids of the rosin, dissolving the resultant product in a liquid solvent, and adding themixture to a motor fuel.

4. The process which comprises heating a distillation product of rosiu, adding thereto a lead oxide in quantity sufiicient to substantially neutralize the acids of. the rosin, and adding said mixture to a motor fuel.

5. The process which comprises heating a distillation product of rosin, adding thereto a lead oxide, and adding said mixture to a motor fuel.

6. The method of making a fuel mixture which comprises providing a distillation product of resinous gum, combining it with an oxide of lead, and adding the mixture to au'explosion motor fuel.

In testimony whereof I, the said JosnrH E. BARB, have hereunto set my hand.

JOSEPH E. BABB.
